初めに、第１コネクタ２０の詳しい構造について主に図２乃至図４を参照しながら説明する。 First, the detailed structure of the first connector 20 will be described mainly with reference to FIGS. 2 to 4.

図２に示すとおり、第１コネクタ２０は、大きな構成要素として第１ハウジング３０と、複数の第１コンタクト４０（コンタクト）と、２つの第１金具５０と、を具備する。 As shown in FIG. 2, the first connector 20 includes a first housing 30, a plurality of first contacts 40 (contacts), and two first metal fittings 50 as large components.

第１ハウジング３０は、絶縁性かつ耐熱性の合成樹脂料によって成形され、左右方向に延在する。第１ハウジング３０は、下部を構成する底板部３１と、底板部３１の上面中央部から上方に突出する嵌合凸部３２と、を具備する。 The first housing 30 is formed of an insulating and heat-resistant synthetic resin material and extends in the left-right direction. The first housing 30 includes a bottom plate portion 31 that constitutes a lower portion, and a fitting convex portion 32 that projects upward from the center of the upper surface of the bottom plate portion 31.

嵌合凸部３２の前壁３２ａ及び後壁３２ｂ並びに底板部３１には、上下方向に沿った複数の第１コンタクト保持溝３３が、左右方向に並んで凹設される。複数の第１コンタクト保持溝３３には、複数の第１コンタクト４０がそれぞれ保持される。複数の第１コンタクト保持溝３３の数は、第１コンタクト４０の数と同一である。 A plurality of first contact holding grooves 33 along the vertical direction are recessed in the front wall 32a, the rear wall 32b, and the bottom plate portion 31 of the fitting convex portion 32 side by side in the left-right direction. A plurality of first contacts 40 are respectively held in the plurality of first contact holding grooves 33. The number of the plurality of first contact holding grooves 33 is the same as the number of the first contacts 40.

底板部３１の左右両端部には、第１金具保持溝３４がそれぞれ貫設される。１対の第１金具保持溝３４には、１対の第１金具５０がそれぞれ保持される。 First metal fitting holding grooves 34 are provided at both left and right ends of the bottom plate portion 31, respectively. A pair of first metal fittings 50 are held in the pair of first metal fittings holding grooves 34, respectively.

嵌合凸部３２の側壁３２ｃの外面Ａ１（第１面）には、凹部３５が形成される。外面Ａ１は、第１コンタクト４０の配列面、すなわち、嵌合凸部３２の前壁３２ａ及び後壁３２ｂの外面と垂直である。凹部３５は、左右両側の側壁３２ｃに一対形成されるのが好適である。凹部３５は、第１コンタクト４０の配列方向、すなわち左右方向に沿って凹むように嵌合凸部３２の外面Ａ１に設けられる。 A recess 35 is formed on the outer surface A1 (first surface) of the side wall 32c of the fitting convex portion 32. The outer surface A1 is perpendicular to the arrangement surface of the first contact 40, that is, the outer surfaces of the front wall 32a and the rear wall 32b of the fitting convex portion 32. It is preferable that the recesses 35 are formed in pairs on the side walls 32c on both the left and right sides. The recess 35 is provided on the outer surface A1 of the fitting convex portion 32 so as to be recessed along the arrangement direction of the first contacts 40, that is, the left-right direction.

第１ハウジング３０は、嵌合凸部３２の側壁３２ｃの上端部に形成された突起部３６を有する。突起部３６は、嵌合凸部３２の側壁３２ｃの外面Ａ１に連続しており、嵌合凸部３２の上面３２ｄに設けられ、嵌合の際に第２ハウジング７０に対して第１ハウジング３０を誘い込む。突起部３６は、第１金具５０よりも嵌合側、すなわち上方に位置する。突起部３６は、嵌合側に向けて徐々に細くなるように傾斜を有している。すなわち、図２に示すように、突起部３６を構成する前後左右の４側面は、上方に向かうにつれて突起部３６が傾斜する傾斜面としてそれぞれ形成される。このように、突起部３６は、前後幅及び左右幅が上方に向かうにつれて減少するような先細り形状として形成される。 The first housing 30 has a protrusion 36 formed at the upper end of the side wall 32c of the fitting protrusion 32. The protrusion 36 is continuous with the outer surface A1 of the side wall 32c of the fitting convex portion 32, is provided on the upper surface 32d of the fitting convex portion 32, and is provided in the first housing 30 with respect to the second housing 70 at the time of fitting. Invite. The protrusion 36 is located on the fitting side, that is, above the first metal fitting 50. The protrusion 36 has an inclination so as to gradually become thinner toward the fitting side. That is, as shown in FIG. 2, the four front, rear, left, and right side surfaces constituting the protrusion 36 are formed as inclined surfaces in which the protrusion 36 is inclined toward the upper side. In this way, the protrusion 36 is formed as a tapered shape in which the front-rear width and the left-right width decrease as the width increases upward.

第１コンタクト４０は、ばね弾性を備えた銅合金（例えば、リン青銅、ベリリウム銅若しくはチタン銅）又はコルソン系銅合金の薄板を順送金型（スタンピング）を用いて成形加工したものである。第１コンタクト４０の表面には、ニッケルメッキで下地を形成した後に、金、錫などのメッキが施される。 The first contact 40 is formed by molding a thin plate of a copper alloy having spring elasticity (for example, phosphor bronze, beryllium copper or titanium copper) or a Corson-based copper alloy using a progressive mold (stamping). The surface of the first contact 40 is plated with gold, tin, or the like after a base is formed by nickel plating.

第１コンタクト４０は、下端部に形成され、前後方向に沿って外側に延出する実装部４１を具備する。第１コンタクト４０は、上部に形成され、前後方向に沿って外側に向いた状態で設けられる第１接触部４２を具備する。 The first contact 40 includes a mounting portion 41 formed at the lower end portion and extending outward along the front-rear direction. The first contact 40 includes a first contact portion 42 formed on the upper portion and provided in a state of facing outward along the front-rear direction.

第１コンタクト４０は、例えば圧入されることで、第１コンタクト保持溝３３に対して保持される。第１コンタクト４０が第１ハウジング３０（第１コンタクト保持溝３３）に保持された状態で、第１コンタクト４０の実装部４１は、底板部３１の下端部から前後方向に沿って外側に突出するように配置される。同様の状態で、第１コンタクト４０の第１接触部４２は、嵌合凸部３２の前壁３２ａ及び後壁３２ｂの外面から前後方向に沿って外側に突出するように配置される。 The first contact 40 is held against the first contact holding groove 33 by, for example, being press-fitted. With the first contact 40 held in the first housing 30 (first contact holding groove 33), the mounting portion 41 of the first contact 40 projects outward from the lower end portion of the bottom plate portion 31 in the front-rear direction. Arranged like this. In the same state, the first contact portion 42 of the first contact 40 is arranged so as to project outward from the outer surfaces of the front wall 32a and the rear wall 32b of the fitting convex portion 32 in the front-rear direction.

第１金具５０は、例えば順送金型（スタンピング）を用いて図４に示すような形状に成形加工したものである。第１金具５０は、左右方向に沿って延在する基部５１と、基部５１の両端で外側に延出するように形成された実装部５２と、を具備する。第１金具５０は、実装部５２の上端から上方に突出する二股状の保持部５３を具備する。第１金具５０は、基部５１の中央部から上方に突出する二股状の突出部５４を具備する。第１金具５０は、突出部５４の上端において、前後両方向に向かってそれぞれ外側に突出する第２接触部５５を具備する。 The first metal fitting 50 is formed into a shape as shown in FIG. 4 by using, for example, a progressive remittance mold (stamping). The first metal fitting 50 includes a base portion 51 extending in the left-right direction, and a mounting portion 52 formed so as to extend outward at both ends of the base portion 51. The first metal fitting 50 includes a bifurcated holding portion 53 that projects upward from the upper end of the mounting portion 52. The first metal fitting 50 includes a bifurcated protruding portion 54 that protrudes upward from the central portion of the base portion 51. The first metal fitting 50 includes a second contact portion 55 that protrudes outward in both the front and rear directions at the upper end of the protruding portion 54.

第１金具５０は、例えば圧入されることで、第１金具保持溝３４に対して保持される（図２参照）。第１金具５０は、二股状の保持部５３が第１ハウジング３０の一部を狭持することで、第１金具保持溝３４に対して保持される。第１金具５０が第１ハウジング３０（第１金具保持溝３４）に保持された状態で、第１金具５０の二股状の突出部５４は、嵌合凸部３２の側壁３２ｃの外面Ａ１に対向して上下方向（嵌合方向）に突出する。同様の状態で、突出部５４は第１ハウジング３０の外部に露出する。特に、突出部５４の二股部分が嵌合凸部３２の側壁３２ｃの外面Ａ１に対向して配置され、突出部５４の二股部分に形成された１対の第２接触部５５の間には、第１ハウジング３０は介在しない。同様の状態で、第２接触部５５は、外面Ａ１と平行な方向、すなわち前後方向に突出するように突出部５４の二股部分に１対設けられる。すなわち、突出部５４は、外面Ａ１と平行な方向、すなわち前後方向に弾性変形する。 The first metal fitting 50 is held against the first metal fitting holding groove 34 by, for example, being press-fitted (see FIG. 2). The first metal fitting 50 is held against the first metal fitting holding groove 34 by the bifurcated holding portion 53 holding a part of the first housing 30. With the first metal fitting 50 held in the first housing 30 (first metal fitting holding groove 34), the bifurcated protrusion 54 of the first metal fitting 50 faces the outer surface A1 of the side wall 32c of the fitting convex portion 32. Then, it protrudes in the vertical direction (fitting direction). In the same state, the protrusion 54 is exposed to the outside of the first housing 30. In particular, the bifurcated portion of the protruding portion 54 is arranged so as to face the outer surface A1 of the side wall 32c of the fitting convex portion 32, and between the pair of second contact portions 55 formed in the bifurcated portion of the protruding portion 54. The first housing 30 does not intervene. In the same state, a pair of second contact portions 55 are provided on the bifurcated portion of the projecting portion 54 so as to project in the direction parallel to the outer surface A1, that is, in the front-rear direction. That is, the protruding portion 54 elastically deforms in the direction parallel to the outer surface A1, that is, in the front-rear direction.

第１金具５０が第１ハウジング３０（第１金具保持溝３４）に保持された状態で、突出部５４の二股部分は、左右方向の側面視において、凹部３５を挟むように配置される。突出部５４は、嵌合凸部３２の側壁３２ｃの外面Ａ１及び凹部３５に近接した状態で、これらの外側に露出して配置される。 In a state where the first metal fitting 50 is held by the first housing 30 (first metal fitting holding groove 34), the bifurcated portion of the protruding portion 54 is arranged so as to sandwich the recess 35 in the lateral view in the left-right direction. The protrusion 54 is arranged so as to be exposed to the outside of the outer surface A1 and the recess 35 of the side wall 32c of the fitting convex portion 32 in a state of being close to the outer surface A1 and the recess 35.

以上構造の第１コネクタ２０では、回路基板ＣＢ１の実装面に形成された回路パターンに対して、第１コンタクト４０の実装部４１がはんだ付けされる。また、当該実装面に形成された接地パターンなどに対して、第１金具５０の実装部５２がはんだ付けされる。以上により、第１コネクタ２０は、回路基板ＣＢ１に対して実装される。回路基板ＣＢ１の実装面には、第１コネクタ２０とは別の電子部品（例えば、ＣＰＵ、コントローラ、メモリなど）が実装される。 In the first connector 20 having the above structure, the mounting portion 41 of the first contact 40 is soldered to the circuit pattern formed on the mounting surface of the circuit board CB1. Further, the mounting portion 52 of the first metal fitting 50 is soldered to the grounding pattern or the like formed on the mounting surface. As described above, the first connector 20 is mounted on the circuit board CB1. An electronic component (for example, a CPU, a controller, a memory, etc.) different from the first connector 20 is mounted on the mounting surface of the circuit board CB1.

続いて、第２コネクタ６０の詳しい構造について主に図５乃至図７を参照しながら説明する。 Subsequently, the detailed structure of the second connector 60 will be described mainly with reference to FIGS. 5 to 7.

図５は、第２コネクタ６０単体を上面視により示した斜視図である。図６は、第２コネクタ６０単体の上面図である。図７は、第２コネクタ６０に保持される第２金具９０の上面視による斜視図である。 FIG. 5 is a perspective view showing the second connector 60 alone in a top view. FIG. 6 is a top view of the second connector 60 alone. FIG. 7 is a perspective view of the second metal fitting 90 held by the second connector 60 from a top view.

図５に示すとおり、第２コネクタ６０は、大きな構成要素として第２ハウジング７０と、複数の第２コンタクト８０と、２つの第２金具９０と、を具備する。 As shown in FIG. 5, the second connector 60 includes a second housing 70, a plurality of second contacts 80, and two second metal fittings 90 as large components.

第２ハウジング７０は、絶縁性かつ耐熱性の合成樹脂料を射出成形した、左右方向に延びる部材である（図５参照）。第２ハウジング７０は、下部を構成する底板部７１と、底板部７１の上面の外周縁部から上方に突出する環状の外周壁７２と、を具備する。環状の外周壁７２の内部に形成された空間は、嵌合凹部７３を構成する。 The second housing 70 is a member extending in the left-right direction, which is formed by injection molding an insulating and heat-resistant synthetic resin material (see FIG. 5). The second housing 70 includes a bottom plate portion 71 that constitutes a lower portion, and an annular outer peripheral wall 72 that projects upward from the outer peripheral edge portion of the upper surface of the bottom plate portion 71. The space formed inside the annular outer peripheral wall 72 constitutes the fitting recess 73.

嵌合凹部７３の前壁７３ａ及び後壁７３ｂ並びに底板部７１には、上下方向に沿った複数の第２コンタクト保持溝７４が、左右方向に並んで凹設される。複数の第２コンタクト保持溝７４には、複数の第２コンタクト８０がそれぞれ保持される。複数の第２コンタクト保持溝７４の数は、第２コンタクト８０の数と同一である。 A plurality of second contact holding grooves 74 along the vertical direction are recessed in the front wall 73a, the rear wall 73b, and the bottom plate portion 71 of the fitting recess 73 side by side in the left-right direction. A plurality of second contacts 80 are respectively held in the plurality of second contact holding grooves 74. The number of the plurality of second contact holding grooves 74 is the same as the number of the second contacts 80.

嵌合凹部７３の左右両端部には、第２金具保持溝７５がそれぞれ凹設される。１対の第２金具保持溝７５には、１対の第２金具９０がそれぞれ保持される。 Second metal fitting holding grooves 75 are recessed at both left and right ends of the fitting recess 73. A pair of second metal fittings 90 are held in the pair of second metal fitting holding grooves 75, respectively.

嵌合凹部７３の側壁７３ｃの内面Ａ２（第２面）には、凸部７６が形成される。凸部７６は、左右両側の側壁７３ｃに一対形成されるのが好適である。凸部７６は、第２コンタクト８０の配列方向、すなわち左右方向に沿って凸となるように嵌合凹部７３の内面Ａ２に設けられる。凸部７６は、凹部３５の形状に対応するように形成されてもよい。特に、凸部７６の前後幅は、凹部３５の前後幅よりもわずかに小さくてもよい。 A convex portion 76 is formed on the inner surface A2 (second surface) of the side wall 73c of the fitting recess 73. It is preferable that the convex portions 76 are formed in pairs on the side walls 73c on both the left and right sides. The convex portion 76 is provided on the inner surface A2 of the fitting recess 73 so as to be convex along the arrangement direction of the second contact 80, that is, the left-right direction. The convex portion 76 may be formed so as to correspond to the shape of the concave portion 35. In particular, the front-rear width of the convex portion 76 may be slightly smaller than the front-rear width of the concave portion 35.

凸部７６の嵌合側の端部、すなわち上端部には、適宜な曲率を有するＲ形状の誘い込み部７７が形成される。誘い込み部７７は、凸部７６の上端面７６ａから嵌合凹部７３の側壁７３ｃと平行な側面７６ｂにかけて略円弧状に形成される。また、誘い込み部７７は、傾斜面によって形成されてもよい。これにより、誘い込み部７７を形成しやすくなる。 An R-shaped inviting portion 77 having an appropriate curvature is formed at the end portion of the convex portion 76 on the fitting side, that is, the upper end portion. The lead-in portion 77 is formed in a substantially arc shape from the upper end surface 76a of the convex portion 76 to the side surface 76b parallel to the side wall 73c of the fitting recess 73. Further, the invitation portion 77 may be formed by an inclined surface. This makes it easier to form the invitation portion 77.

第２コンタクト８０は、銅合金（例えば、リン青銅、ベリリウム銅若しくはチタン銅）又はコルソン系銅合金の薄板を順送金型（スタンピング）を用いて成形加工したものである。第２コンタクト８０の表面には、ニッケルメッキで下地を形成した後に、金、錫などのメッキが施される。 The second contact 80 is formed by molding a thin plate of a copper alloy (for example, phosphor bronze, beryllium copper or titanium copper) or a Corson-based copper alloy using a progressive mold (stamping). The surface of the second contact 80 is plated with gold, tin, or the like after a base is formed by nickel plating.

第２コンタクト８０は、下端部に形成され、前後方向に沿って外側に延出する実装部８１を具備する。第２コンタクト８０は、上部に形成され、前後方向に沿って内側に向いた状態で設けられる第３接触部８２を具備する。第３接触部８２は、上下方向に沿った所定の領域にわたって延在する。 The second contact 80 includes a mounting portion 81 formed at the lower end portion and extending outward along the front-rear direction. The second contact 80 includes a third contact portion 82 formed on the upper portion and provided in a state of facing inward along the front-rear direction. The third contact portion 82 extends over a predetermined region along the vertical direction.

第２コンタクト８０は、例えば圧入されることで、第２コンタクト保持溝７４に対して保持される。第２コンタクト８０が第２ハウジング７０（第２コンタクト保持溝７４）に保持された状態で、第２コンタクト８０の実装部８１は、底板部７１の下端部から前後方向に沿って外側に突出するように配置される。同様の状態で、第２コンタクト８０の第３接触部８２は、嵌合凹部７３の前壁７３ａ及び後壁７３ｂの内面において前後方向に沿って内側に向くように配置される。 The second contact 80 is held against the second contact holding groove 74 by, for example, being press-fitted. With the second contact 80 held in the second housing 70 (second contact holding groove 74), the mounting portion 81 of the second contact 80 projects outward from the lower end portion of the bottom plate portion 71 in the front-rear direction. Arranged like this. In the same state, the third contact portion 82 of the second contact 80 is arranged so as to face inward along the front-rear direction on the inner surfaces of the front wall 73a and the rear wall 73b of the fitting recess 73.

第２金具９０は、例えば順送金型（スタンピング）を用いて図７に示すような形状に成形加工したものである。第２金具９０は、左右方向に沿って延在する基部９１と、基部９１の両端で外側に延出するように形成された実装部９２と、を具備する。第２金具９０は、基部９１の中央部から上方に突出する保持部９３を具備する。第２金具９０は、保持部９３を挟むように基部９１から上方に突出する二股状の突出部９４を具備する。第２金具９０は、突出部９４の上端において、前後両方向に向かってそれぞれ内側に突出する突部９５を具備する。 The second metal fitting 90 is formed into a shape as shown in FIG. 7 by using, for example, a progressive remittance mold (stamping). The second metal fitting 90 includes a base portion 91 extending in the left-right direction, and a mounting portion 92 formed so as to extend outward at both ends of the base portion 91. The second metal fitting 90 includes a holding portion 93 that projects upward from the central portion of the base portion 91. The second metal fitting 90 includes a bifurcated protruding portion 94 that protrudes upward from the base portion 91 so as to sandwich the holding portion 93. The second metal fitting 90 includes a protrusion 95 that protrudes inward in both the front and rear directions at the upper end of the protrusion 94.

第２金具９０は、例えば圧入されることで、第２金具保持溝７５に対して保持される（図５参照）。特に、第２金具９０は、保持部９３が第２金具保持溝７５の一部に圧入されることで、第２金具保持溝７５に対して保持される。保持部９３は、第２金具９０が第２ハウジング７０（第２金具保持溝７５）に保持された状態で、嵌合凹部７３の側壁７３ｃの内面Ａ２に形成された凸部７６の内部に位置する。同様の状態で、第２金具９０の二股状の突出部９４は、嵌合凹部７３の側壁７３ｃの内面Ａ２に対向して上下方向（嵌合方向）に突出する。突出部９４の二股部分は、嵌合凹部７３の側壁７３ｃの内面Ａ２に対向して配置され、突出部９４の二股部分の間には、凸部７６が配置される。このように、第２金具９０は、凸部７６を挟んだ状態で第２ハウジング７０に保持される。 The second metal fitting 90 is held against the second metal fitting holding groove 75 by, for example, being press-fitted (see FIG. 5). In particular, the second metal fitting 90 is held against the second metal fitting holding groove 75 by press-fitting the holding portion 93 into a part of the second metal fitting holding groove 75. The holding portion 93 is located inside the convex portion 76 formed on the inner surface A2 of the side wall 73c of the fitting recess 73 in a state where the second metal fitting 90 is held by the second housing 70 (second metal fitting holding groove 75). To do. In the same state, the bifurcated protruding portion 94 of the second metal fitting 90 projects in the vertical direction (fitting direction) facing the inner surface A2 of the side wall 73c of the fitting recess 73. The bifurcated portion of the protruding portion 94 is arranged so as to face the inner surface A2 of the side wall 73c of the fitting recess 73, and the convex portion 76 is arranged between the bifurcated portions of the protruding portion 94. In this way, the second metal fitting 90 is held in the second housing 70 with the convex portion 76 sandwiched between them.

以上構造の第２コネクタ６０は、回路基板ＣＢ１と平行な板材である回路基板ＣＢ２の一方の面に形成した実装面に実装される。具体的には、第２コンタクト８０の実装部８１が、回路基板ＣＢ２の実装面に形成された回路パターンに対してはんだ付けされる。また、第２金具９０の実装部９２が、当該実装面に形成された接地パターンなどに対してはんだ付けされる。以上により、第２コネクタ６０は、回路基板ＣＢ２に対して実装される。回路基板ＣＢ２の実装面には、第２コネクタ６０とは別の電子部品（例えば、高機能用モジュール、半導体、大容量メモリなど）が実装される。 The second connector 60 having the above structure is mounted on a mounting surface formed on one surface of the circuit board CB2, which is a plate material parallel to the circuit board CB1. Specifically, the mounting portion 81 of the second contact 80 is soldered to the circuit pattern formed on the mounting surface of the circuit board CB2. Further, the mounting portion 92 of the second metal fitting 90 is soldered to a grounding pattern or the like formed on the mounting surface. As described above, the second connector 60 is mounted on the circuit board CB2. An electronic component (for example, a high-performance module, a semiconductor, a large-capacity memory, etc.) different from the second connector 60 is mounted on the mounting surface of the circuit board CB2.

続いて、第１コネクタ２０に対して第２コネクタ６０を接続する要領について説明する。 Subsequently, a procedure for connecting the second connector 60 to the first connector 20 will be described.

図８は、第１コネクタ２０と第２コネクタ６０とが嵌合した状態で電気コネクタ１０を上面視により示した斜視図である。図９は、図８のIX−IX矢線に沿った拡大断面図である。図１０は、図８のX-X矢線に沿った断面図である。 FIG. 8 is a perspective view showing the electric connector 10 in a top view with the first connector 20 and the second connector 60 fitted together. FIG. 9 is an enlarged cross-sectional view taken along the IX-IX arrow line of FIG. FIG. 10 is a cross-sectional view taken along the line XX of FIG.

初めに、図１に示すように、第１コネクタ２０の上下方向の向きを逆にした状態で、第１コネクタ２０と第２コネクタ６０との前後位置及び左右位置を略一致させながら、互いを上下方向に対向させる。そして、第１コネクタ２０を下方に移動させる。このとき、互いの位置が例えば前後左右方向に多少ずれていても、上述のとおり、第１コネクタ２０の突起部３６が嵌合凸部３２の上面３２ｄに設けられるので、突起部３６が最初に第２コネクタ６０と接触する。突起部３６は、嵌合側に向かうにつれて傾斜する傾斜面として構成されるので、第２コネクタ６０、特に第２ハウジング７０に接触した段階から第１ハウジング３０を誘い込むように機能する。すなわち、互いの位置が前後左右方向に多少ずれていても、第１コネクタ２０は、突起部３６により、第２コネクタ６０と嵌合するための最適位置に誘い込まれる。さらに、第２コネクタ６０の凸部７６の嵌合側の端部に設けられたＲ形状の誘い込み部７７によって、突起部３６によって誘い込まれた第１コネクタ２０が、嵌合凹部７３の内部へとさらに誘い込まれる。このとき、第１コネクタ２０の前後方向の位置は、第２コネクタ６０の嵌合凹部７３の前壁７３ａ及び後壁７３ｂを基準にして決定される。 First, as shown in FIG. 1, in a state where the vertical direction of the first connector 20 is reversed, the front-rear position and the left-right position of the first connector 20 and the second connector 60 are substantially matched with each other. Face each other in the vertical direction. Then, the first connector 20 is moved downward. At this time, even if the positions are slightly deviated from each other in the front-back and left-right directions, for example, as described above, the protrusion 36 of the first connector 20 is provided on the upper surface 32d of the fitting convex portion 32, so that the protrusion 36 is first. Contact with the second connector 60. Since the protrusion 36 is configured as an inclined surface that inclines toward the fitting side, it functions to lure the first housing 30 from the stage of contact with the second connector 60, particularly the second housing 70. That is, even if the positions of the first connector 20 are slightly deviated from each other in the front-back and left-right directions, the protrusion 36 invites the first connector 20 to the optimum position for fitting with the second connector 60. Further, the first connector 20 attracted by the protrusion 36 by the R-shaped attracting portion 77 provided at the end of the convex portion 76 of the second connector 60 on the fitting side is moved into the fitting recess 73. Is further invited. At this time, the position of the first connector 20 in the front-rear direction is determined with reference to the front wall 73a and the rear wall 73b of the fitting recess 73 of the second connector 60.

第１コネクタ２０をさらに下方へと移動させると、第１金具５０の第２接触部５５が第２金具９０の突部９５と接触して、突出部５４が内側へとわずかに弾性変形する。突出部５４が内側へとわずかに弾性変形すると共に、第２接触部５５は、突部９５に対して下方へと摺動する。第２接触部５５が突部９５を乗り越えると、突出部５４の弾性変形がわずかに緩和する。この状態のまま、第２接触部５５は、第２金具９０の突出部９４の内面に対して摺動する。 When the first connector 20 is further moved downward, the second contact portion 55 of the first metal fitting 50 comes into contact with the protrusion 95 of the second metal fitting 90, and the protruding portion 54 is slightly elastically deformed inward. The protruding portion 54 is slightly elastically deformed inward, and the second contact portion 55 slides downward with respect to the protruding portion 95. When the second contact portion 55 gets over the protrusion 95, the elastic deformation of the protrusion 54 is slightly relaxed. In this state, the second contact portion 55 slides with respect to the inner surface of the protruding portion 94 of the second metal fitting 90.

第１コネクタ２０をさらに下方へと移動させ、嵌合凸部３２が第２コネクタ６０の嵌合凹部７３の内部に完全に侵入すると、第１コネクタ２０と第２コネクタ６０とが互いに嵌合する。さらに、第１金具５０と第２金具９０とが互いに係合する。この状態で、第１コンタクト４０の第１接触部４２と第２コンタクト８０の第３接触部８２とが接触する。第１コンタクト４０は、第１接触部４２の接触に伴う第３接触部８２からの垂直抗力によって第１接触部４２の近傍で内側へとわずかに弾性変形する。同様の状態で、第１金具５０の第２接触部５５が第２金具９０と接触する（図１０参照）。第１金具５０では、第２接触部５５の接触に伴う第２金具９０からの垂直抗力によって、突出部５４が内側へとわずかに弾性変形する。すなわち、突出部５４の二股部分の間隔が、何の外力も働かない自由状態における当該間隔よりもわずかに減少する。 When the first connector 20 is further moved downward and the fitting protrusion 32 completely penetrates into the fitting recess 73 of the second connector 60, the first connector 20 and the second connector 60 are fitted to each other. .. Further, the first metal fitting 50 and the second metal fitting 90 engage with each other. In this state, the first contact portion 42 of the first contact 40 and the third contact portion 82 of the second contact 80 come into contact with each other. The first contact 40 is slightly elastically deformed inward in the vicinity of the first contact portion 42 by the normal force from the third contact portion 82 accompanying the contact of the first contact portion 42. In the same state, the second contact portion 55 of the first metal fitting 50 comes into contact with the second metal fitting 90 (see FIG. 10). In the first metal fitting 50, the protruding portion 54 is slightly elastically deformed inward due to the normal force from the second metal fitting 90 accompanying the contact of the second contact portion 55. That is, the distance between the bifurcated portions of the protrusion 54 is slightly smaller than the distance in the free state in which no external force acts.

以上により、第１コネクタ２０と第２コネクタ６０とは、互いに完全に接続される。すなわち、第１コンタクト４０と第２コンタクト８０とが電気的に接続され、第１金具５０と第２金具９０とが電気的に接続される。これにより、第１コンタクト４０及び第２コンタクト８０などを介して、回路基板ＣＢ１と回路基板ＣＢ２とが電気的に導通可能になる。 As described above, the first connector 20 and the second connector 60 are completely connected to each other. That is, the first contact 40 and the second contact 80 are electrically connected, and the first metal fitting 50 and the second metal fitting 90 are electrically connected. As a result, the circuit board CB1 and the circuit board CB2 can be electrically conductive via the first contact 40, the second contact 80, and the like.

このとき、図９に示すとおり、第２ハウジング７０の凸部７６は、第１ハウジング３０の凹部３５と嵌合する。凸部７６は、第２金具９０と係合した第１金具５０の弾性変形方向、すなわち前後方向に当該第１金具５０と近接して配置される。凸部７６は、外面Ａ１に垂直な方向、すなわち左右方向に沿った側面７６ｃが第１金具５０と対向するように配置される。特に、凸部７６は、第２金具９０と係合した第１金具５０によって挟まれる。より詳細には、第１金具５０の二股状の突出部５４が第２金具９０の二股状の突出部９４によって前後方向に沿って挟まれ、第２ハウジング７０の凸部７６が第１金具５０の二股状の突出部５４によって前後方向に沿って挟まれる。このように、凸部７６は、左右方向において、第１金具５０よりも凹部３５側に突出するように配置される。より具体的には、互いに嵌合した状態で、第１ハウジング３０の嵌合凸部３２の側壁３２ｃと対向する凸部７６の側面７６ｂは、左右方向において突出部５４及び突出部９４よりも凹部３５側に位置する。凸部７６は、左右方向に対する嵌合面が第１金具５０及び第２金具９０よりも内側に突出した状態で、凹部３５と嵌合する。 At this time, as shown in FIG. 9, the convex portion 76 of the second housing 70 fits with the concave portion 35 of the first housing 30. The convex portion 76 is arranged close to the first metal fitting 50 in the elastic deformation direction of the first metal fitting 50 engaged with the second metal fitting 90, that is, in the front-rear direction. The convex portion 76 is arranged so that the side surface 76c along the direction perpendicular to the outer surface A1, that is, the left-right direction faces the first metal fitting 50. In particular, the convex portion 76 is sandwiched by the first metal fitting 50 that is engaged with the second metal fitting 90. More specifically, the bifurcated protrusion 54 of the first metal fitting 50 is sandwiched by the bifurcated protrusion 94 of the second metal fitting 90 along the front-rear direction, and the convex portion 76 of the second housing 70 is the first metal fitting 50. It is sandwiched along the front-rear direction by the bifurcated protrusion 54 of the above. In this way, the convex portion 76 is arranged so as to project toward the concave portion 35 side with respect to the first metal fitting 50 in the left-right direction. More specifically, the side surface 76b of the convex portion 76 facing the side wall 32c of the fitting convex portion 32 of the first housing 30 in a state of being fitted to each other is recessed more than the protruding portion 54 and the protruding portion 94 in the left-right direction. It is located on the 35th side. The convex portion 76 is fitted with the concave portion 35 in a state where the fitting surface in the left-right direction protrudes inward from the first metal fitting 50 and the second metal fitting 90.

また、図１０に示すとおり、第１ハウジング３０及び第２ハウジング７０の嵌合後において、第１金具５０の突出部５４と凸部７６との間に空隙Ｓが形成される。特に、第１金具５０の突出部５４は、わずかに弾性変形して第２金具９０と係合した状態であっても第２ハウジング７０の凸部７６には接触しない。二股状の突出部５４と凸部７６との間には突出部５４の二股部分のさらなる弾性変形を可能とする余剰空間が形成される一方で、突出部５４と凸部７６とは近接する。特に、突出部５４と凸部７６とは、突出部５４の二股部分の過剰な弾性変形を規制できる程度に近接する。この場合、第１ハウジング３０と第２ハウジング７０とが嵌合する際に、仮に、斜め嵌合の状態で第１金具５０が多少弾性変形した場合であっても、突出部５４と凸部７６とは、凸部７６が第１金具５０を支持できる程度に近接する。 Further, as shown in FIG. 10, after the first housing 30 and the second housing 70 are fitted, a gap S is formed between the protruding portion 54 and the convex portion 76 of the first metal fitting 50. In particular, the protruding portion 54 of the first metal fitting 50 does not come into contact with the convex portion 76 of the second housing 70 even when it is slightly elastically deformed and engaged with the second metal fitting 90. An extra space is formed between the bifurcated protrusion 54 and the convex portion 76 to allow further elastic deformation of the bifurcated portion of the protruding portion 54, while the protruding portion 54 and the convex portion 76 are close to each other. In particular, the protruding portion 54 and the convex portion 76 are close to each other to such an extent that excessive elastic deformation of the bifurcated portion of the protruding portion 54 can be regulated. In this case, when the first housing 30 and the second housing 70 are fitted together, even if the first metal fitting 50 is slightly elastically deformed in the obliquely fitted state, the protruding portion 54 and the convex portion 76 Is close enough that the convex portion 76 can support the first metal fitting 50.

以上のような電気コネクタ１０は、第１金具５０と凸部７６との近接配置及び突起部３６の構成によって、小型化においてもハウジングの破損及び金具の過剰な変形を防止できる。すなわち、第１金具５０の過剰な弾性変形が凸部７６によって規制されるので、電気コネクタ１０は、嵌合の際に第１金具５０が過度に変形する可能性を低減できる。例えば、第１ハウジング３０と第２ハウジング７０とが嵌合する際に、斜め嵌合の状態で第１金具５０が多少弾性変形した場合であっても、第２ハウジング７０に形成された凸部７６が第１金具５０を支持するので、電気コネクタ１０は、第１金具５０の過剰な変形を防止できる。また、電気コネクタ１０は、第１ハウジング３０の突起部３６が第１金具５０よりも嵌合側に位置することで、嵌合の際に金具及びハウジングを適切に保護できる。すなわち、嵌合の際に第１コネクタ２０及び第２コネクタ６０の相対位置が前後左右方向にわずかにずれていたとしても、第２コネクタ６０に最初に接触する部分は突起部３６である。このように、電気コネクタ１０は、嵌合の際に第１金具５０が適切な位置に挿入される前に第２コネクタ６０の一部と接触して金具が過度に変形又はハウジングが破損することを防止できる。 In the electric connector 10 as described above, the housing can be prevented from being damaged and the metal fittings can be prevented from being excessively deformed even in miniaturization by the proximity arrangement of the first metal fitting 50 and the convex portion 76 and the configuration of the protrusion 36. That is, since the excessive elastic deformation of the first metal fitting 50 is regulated by the convex portion 76, the electric connector 10 can reduce the possibility that the first metal fitting 50 is excessively deformed at the time of fitting. For example, when the first housing 30 and the second housing 70 are fitted together, even if the first metal fitting 50 is slightly elastically deformed in the obliquely fitted state, the convex portion formed on the second housing 70. Since the 76 supports the first metal fitting 50, the electric connector 10 can prevent the first metal fitting 50 from being excessively deformed. Further, in the electric connector 10, the protrusion 36 of the first housing 30 is located closer to the fitting side than the first metal fitting 50, so that the metal fitting and the housing can be appropriately protected at the time of fitting. That is, even if the relative positions of the first connector 20 and the second connector 60 are slightly displaced in the front-rear and left-right directions at the time of fitting, the portion that first contacts the second connector 60 is the protrusion 36. As described above, the electric connector 10 comes into contact with a part of the second connector 60 before the first metal fitting 50 is inserted into an appropriate position at the time of fitting, and the metal fitting is excessively deformed or the housing is damaged. Can be prevented.

凸部７６が凹部３５と嵌合することで、第１コネクタ２０及び第２コネクタ６０は、嵌合の際に互いに誘い込まれる。したがって、電気コネクタ１０は、第１コネクタ２０及び第２コネクタ６０同士の嵌合性を向上できる。同様に、凸部７６と凹部３５との嵌合によって、第１コネクタ２０及び第２コネクタ６０の一方に対する他方の位置決めが容易となる。 By fitting the convex portion 76 with the concave portion 35, the first connector 20 and the second connector 60 are attracted to each other at the time of fitting. Therefore, the electric connector 10 can improve the fitability between the first connector 20 and the second connector 60. Similarly, the fitting of the convex portion 76 and the concave portion 35 facilitates the positioning of the other with respect to one of the first connector 20 and the second connector 60.

電気コネクタ１０は、凸部７６及び凹部３５による嵌合構造によって、第１コネクタ２０及び第２コネクタ６０の嵌合力を向上できる。このように、電気コネクタ１０は、小型化した状態であっても、嵌合力を向上できる。さらに、電気コネクタ１０は、第１金具５０及び第２金具９０が係合することで、第１コネクタ２０と第２コネクタ６０との接続をより強固にできる。 The fitting structure of the convex portion 76 and the concave portion 35 of the electric connector 10 can improve the fitting force of the first connector 20 and the second connector 60. As described above, the electric connector 10 can improve the fitting force even in a miniaturized state. Further, in the electric connector 10, the connection between the first connector 20 and the second connector 60 can be further strengthened by engaging the first metal fitting 50 and the second metal fitting 90.

電気コネクタ１０は、第１金具５０の突出部５４が第１ハウジング３０の外部に露出することで、対応する部分を第１ハウジング３０によって覆う必要がなく、第１コネクタ２０を小型化できる。特に、電気コネクタ１０は、第１コンタクト４０の配列方向、すなわち左右方向に対して第１コネクタ２０を小型化できる。すなわち、第１コネクタ２０は、回路基板ＣＢ１における専有面積を低減して、回路基板ＣＢ１全体の省スペース化に寄与できる。 In the electric connector 10, since the protruding portion 54 of the first metal fitting 50 is exposed to the outside of the first housing 30, it is not necessary to cover the corresponding portion with the first housing 30, and the first connector 20 can be miniaturized. In particular, the electric connector 10 can reduce the size of the first connector 20 in the arrangement direction of the first contacts 40, that is, in the left-right direction. That is, the first connector 20 can reduce the occupied area of the circuit board CB1 and contribute to space saving of the entire circuit board CB1.

電気コネクタ１０は、突出部５４が二股状に形成されることで、第１金具５０のある程度の弾性変形を容易とする。電気コネクタ１０は、突出部５４の二股部分の間に第１ハウジング３０が介在しないことで、第１コネクタ２０をより小型化できる。さらに、電気コネクタ１０は、嵌合の際に第１金具５０の突出部５４の内側への弾性変形量を確保することができ、小型化した状態であっても第１金具５０及び第２金具９０同士の係合力を向上できる。 In the electric connector 10, the protruding portion 54 is formed in a bifurcated shape, which facilitates a certain degree of elastic deformation of the first metal fitting 50. The electric connector 10 can be made smaller by not interposing the first housing 30 between the bifurcated portions of the protruding portions 54. Further, the electric connector 10 can secure the amount of elastic deformation inward of the protruding portion 54 of the first metal fitting 50 at the time of fitting, and the first metal fitting 50 and the second metal fitting even in a miniaturized state. The engaging force between 90s can be improved.

電気コネクタ１０は、第１金具５０の第２接触部５５を前後方向に向けることで、第１コネクタ２０を左右方向に小型化できる。すなわち、第１金具５０の第２接触部５５が前後方向に沿って突出部５４の二股部分に設けられ、第２金具９０との係合の際に、突出部５４が前後方向に弾性変形するので、左右方向において第１金具５０が弾性変形するための空間を設ける必要がない。一方で、凹部３５が突出部５４の二股部分の間に位置するので、電気コネクタ１０は、前後方向における第１金具５０の弾性変形空間を確保できる。このように、第１金具５０と第２金具９０との係合構造が前後方向に沿っているので、電気コネクタ１０は、全体として左右方向に小型化できる。 The electric connector 10 can reduce the size of the first connector 20 in the left-right direction by directing the second contact portion 55 of the first metal fitting 50 in the front-rear direction. That is, the second contact portion 55 of the first metal fitting 50 is provided at the bifurcated portion of the protruding portion 54 along the front-rear direction, and the protruding portion 54 is elastically deformed in the front-rear direction when engaged with the second metal fitting 90. Therefore, it is not necessary to provide a space for the first metal fitting 50 to be elastically deformed in the left-right direction. On the other hand, since the concave portion 35 is located between the bifurcated portions of the protruding portion 54, the electric connector 10 can secure an elastic deformation space of the first metal fitting 50 in the front-rear direction. As described above, since the engaging structure of the first metal fitting 50 and the second metal fitting 90 is along the front-rear direction, the electric connector 10 can be miniaturized in the left-right direction as a whole.

電気コネクタ１０は、嵌合後において突出部５４と凸部７６との間に形成される空隙Ｓにより、突出部５４の多少の弾性変形を許容できる。これにより、電気コネクタ１０は、第１金具５０及び第２金具９０の係合をより強固にでき、第１コネクタ２０と第２コネクタ６０との嵌合力を向上できる。電気コネクタ１０は、小型化した状態であっても、第１金具５０及び第２金具９０同士の接触安定性を維持できる。一方で、電気コネクタ１０は、第１金具５０と凸部７６との近接配置及び突起部３６の構成によって、小型化においても金具の過剰な変形を防止できる。すなわち、第１金具５０の過剰な弾性変形が凸部７６によって規制されるので、電気コネクタ１０は、嵌合の際に第１金具５０が過度に変形する可能性を低減できる。 The electric connector 10 can tolerate some elastic deformation of the protruding portion 54 due to the gap S formed between the protruding portion 54 and the convex portion 76 after fitting. As a result, the electric connector 10 can strengthen the engagement between the first metal fitting 50 and the second metal fitting 90, and can improve the fitting force between the first connector 20 and the second connector 60. The electric connector 10 can maintain the contact stability between the first metal fitting 50 and the second metal fitting 90 even in a miniaturized state. On the other hand, the electric connector 10 can prevent excessive deformation of the metal fitting even in miniaturization due to the proximity arrangement of the first metal fitting 50 and the convex portion 76 and the configuration of the protrusion 36. That is, since the excessive elastic deformation of the first metal fitting 50 is regulated by the convex portion 76, the electric connector 10 can reduce the possibility that the first metal fitting 50 is excessively deformed at the time of fitting.

電気コネクタ１０は、突起部３６を嵌合側に向けて先細りとなるように形成することで、誘い込み性をさらに向上できる。すなわち、電気コネクタ１０は、突起部３６の傾斜面が第２ハウジング７０に接触することで、第１コネクタ２０の嵌合方向への押し込み力を嵌合凹部７３の内側へと向く誘い込み力に変換できる。これにより、電気コネクタ１０は、嵌合性をさらに向上できる。 By forming the protrusion 36 so as to taper toward the fitting side, the electrical connector 10 can be further improved in attracting property. That is, in the electric connector 10, when the inclined surface of the protrusion 36 comes into contact with the second housing 70, the pushing force of the first connector 20 in the fitting direction is converted into an inviting force toward the inside of the fitting recess 73. it can. Thereby, the electric connector 10 can further improve the fitability.

電気コネクタ１０は、第１コンタクト４０の配列方向、すなわち左右方向に沿って凹むように凹部３５が設けられることで、第１ハウジング３０及び第２ハウジング７０の左右方向に対する位置決めを容易にする。 The electric connector 10 is provided with a recess 35 so as to be recessed along the arrangement direction of the first contacts 40, that is, the left-right direction, thereby facilitating the positioning of the first housing 30 and the second housing 70 in the left-right direction.

電気コネクタ１０は、凸部７６の形状を凹部３５に対応させることで、第１コネクタ２０及び第２コネクタ６０の嵌合の際の誘い込み性をさらに向上できる。すなわち、電気コネクタ１０は、互いの嵌合性をより向上できる。同様に、電気コネクタ１０は、第１コネクタ２０及び第２コネクタ６０の嵌合力をさらに向上できる。 By making the shape of the convex portion 76 correspond to the concave portion 35, the electric connector 10 can further improve the attractiveness when the first connector 20 and the second connector 60 are fitted. That is, the electric connectors 10 can further improve the fitability of each other. Similarly, the electric connector 10 can further improve the fitting force of the first connector 20 and the second connector 60.

電気コネクタ１０は、第２ハウジング７０の凸部７６の上端部に誘い込み部７７を設けることで、第１コネクタ２０の嵌合の際の誘い込み性をさらに向上でき、第１コネクタ２０及び第２コネクタ６０の嵌合性をさらに向上できる。 By providing the lead-in portion 77 at the upper end of the convex portion 76 of the second housing 70, the electric connector 10 can further improve the pull-in property when the first connector 20 is fitted, and the first connector 20 and the second connector can be provided. The fitability of the 60 can be further improved.

電気コネクタ１０は、第２金具９０の突部９５が第１コネクタ２０の抜去方向における乗り越え壁の役割を果たすことで、抜止作用を実現できる。このように、電気コネクタ１０は、嵌合の際の保持力を向上できる。 The electric connector 10 can realize a retaining action by the protrusion 95 of the second metal fitting 90 acting as an overcoming wall in the removal direction of the first connector 20. In this way, the electric connector 10 can improve the holding force at the time of fitting.

本発明は、その精神又はその本質的な特徴から離れることなく、上述した実施形態以外の他の所定の形態で実現できることは当業者にとって明白である。したがって、先の記述は例示的なものであり、これに限定されるものではない。発明の範囲は、先の記述によってではなく、付加した請求項によって定義される。あらゆる変更のうちその均等の範囲内にあるいくつかの変更は、その中に包含されるものとする。 It will be apparent to those skilled in the art that the present invention can be realized in certain forms other than those described above without departing from its spirit or its essential features. Therefore, the above description is exemplary and is not limited thereto. The scope of the invention is defined by the appended claims, not by the earlier description. Some of all changes that are within their equality shall be included therein.

図１１は、一実施形態に係る電気コネクタ１０の変形例を示した図９に対応する拡大断面図である。例えば、図１１に示すとおり、外面Ａ１に垂直な方向、すなわち左右方向に沿った第２ハウジング７０の凸部７６の側面７６ｃは、左右方向に平行でなくてもよい。すなわち、凸部７６の側面７６ｃは、左右方向に対して傾斜する任意の傾斜面であってもよいし、任意の曲面であってもよい。 FIG. 11 is an enlarged cross-sectional view corresponding to FIG. 9 showing a modified example of the electric connector 10 according to the embodiment. For example, as shown in FIG. 11, the side surface 76c of the convex portion 76 of the second housing 70 along the direction perpendicular to the outer surface A1, that is, the left-right direction does not have to be parallel to the left-right direction. That is, the side surface 76c of the convex portion 76 may be an arbitrary inclined surface that is inclined with respect to the left-right direction, or may be an arbitrary curved surface.

例えば、第１ハウジング３０の凹部３５及び第２ハウジング７０の凸部７６の構造を入れ替えて、第１ハウジング３０が凸部を有し、第２ハウジング７０が対応する凹部を有してもよい。 For example, the structures of the concave portion 35 of the first housing 30 and the convex portion 76 of the second housing 70 may be exchanged so that the first housing 30 has the convex portion and the second housing 70 has the corresponding concave portion.

第２ハウジング７０の凸部７６の左右方向に対する嵌合面の位置は、図９に示すような位置に限定されず、凸部７６が第１金具５０の過剰な弾性変形を規制できる任意の位置であってよい。例えば、図９において、当該嵌合面は、第１金具５０及び第２金具９０の右端面よりも若干左側に位置してもよい。 The position of the fitting surface of the convex portion 76 of the second housing 70 with respect to the left-right direction is not limited to the position shown in FIG. 9, and the convex portion 76 can regulate excessive elastic deformation of the first metal fitting 50 at an arbitrary position. It may be. For example, in FIG. 9, the fitting surface may be located slightly to the left of the right end surfaces of the first metal fitting 50 and the second metal fitting 90.

第１金具５０及び第２金具９０並びに凸部７６の位置関係は、図９に示すような関係に限定されない。例えば、第１金具５０の突出部５４が最も外側に位置し、第２金具９０の突出部９４が突出部５４と凸部７６との間に位置してもよい。この場合、凸部７６の側面７６ｃは、第２金具９０、特に突出部９４と対向する。 The positional relationship between the first metal fitting 50, the second metal fitting 90, and the convex portion 76 is not limited to the relationship shown in FIG. For example, the protruding portion 54 of the first metal fitting 50 may be located on the outermost side, and the protruding portion 94 of the second metal fitting 90 may be located between the protruding portion 54 and the convex portion 76. In this case, the side surface 76c of the convex portion 76 faces the second metal fitting 90, particularly the protruding portion 94.

第１金具５０の突出部５４は、図２のような露出状態に限定されず、第１コネクタ２０の小型化に寄与できれば、任意の露出状態で構成されてもよい。例えば、突出部５４の二股部分の間には、第１ハウジング３０が介在してもよい。 The protruding portion 54 of the first metal fitting 50 is not limited to the exposed state as shown in FIG. 2, and may be configured in any exposed state as long as it can contribute to the miniaturization of the first connector 20. For example, the first housing 30 may be interposed between the bifurcated portions of the protruding portions 54.

第１金具５０及び第２金具９０は、圧入によって第１ハウジング３０及び第２ハウジング７０にそれぞれ保持される構成に限定されず、インサート成形によって保持されてもよい。 The first metal fitting 50 and the second metal fitting 90 are not limited to the configuration in which they are held in the first housing 30 and the second housing 70 by press fitting, respectively, and may be held by insert molding.

第２金具９０は、図５に示すとおり、第２ハウジング７０内に配置される構成に限定されない。例えば、第２金具９０は、第１金具５０同様、第２ハウジング７０の外部に露出してもよい。これにより、電気コネクタ１０は、第１コネクタ２０のみならず、第２コネクタ６０の小型化にも寄与できる。 As shown in FIG. 5, the second metal fitting 90 is not limited to the configuration arranged in the second housing 70. For example, the second metal fitting 90 may be exposed to the outside of the second housing 70 like the first metal fitting 50. As a result, the electric connector 10 can contribute to the miniaturization of not only the first connector 20 but also the second connector 60.
